Products Description
Mercury sulphide, also known as cinnabar, is a mineral that is typically red in color and has been used for various purposes throughout history. It is composed of mercury and sulfur and is known for its vibrant color and unique properties.
Basic properties
- Chemical structure: The hydroxyl group (-OH) on the glucose unit of cellulose is replaced by a carboxymethyl group (-CH₂COOH), and the degree of substitution (DS) is usually 0.6~1.2.
- Solubility: Easily soluble in water, insoluble in organic solvents (such as ethanol, acetone).
- Solution properties:
- High viscosity (depending on molecular weight and degree of substitution).
- pH stability: Stable in the pH range of 3~12, and precipitation may occur if the acid is too strong (pH < 3).
- Salt resistance: May gel under the influence of high-valent metal ions (Ca²⁺, Al³⁺).
- Biocompatibility: non-toxic, non-irritating, biodegradable (but the degradation rate is slow).
Main application areas
(1) Food industry (E466 food additives)**
- Thickener: used in ice cream, yogurt, sauces, etc. to improve consistency and stability.
- Water-retaining agent: delays water loss in baked goods and extends shelf life.
- Emulsifier stabilizer: prevents beverages (such as juice, protein drinks) from stratifying.
(2) Medicine and cosmetics
- Drug sustained release: used as tablet binder or sustained release matrix.
- Artificial tears: used in eye drops to provide lubrication.
- **Toothpaste/skin care products**: thickens and stabilizes emulsions.
(3) Industrial applications
- Oil drilling: used as drilling fluid viscosity enhancer to reduce water loss.
- Textile printing and dyeing: used as slurry to improve fiber adhesion.
- Paper industry: Enhance paper strength and improve coating performance.
(4) Tobacco industry (potential applications)
- Reconstituted tobacco adhesive: Replace traditional adhesives (such as PVA) and reduce the release of harmful substances.
- Filter rod additive: Research is used to improve filtration performance (but acetate fiber is still the mainstream).
characteristics
One of the key characteristics of CMC is its ability to form viscous solutions in water. This property makes it an ideal thickening agent in many products, such as food items, cosmetics, and pharmaceutical formulations. In food products, CMC is used to improve texture, stability, and mouthfeel. It is commonly found in ice creams, baked goods, and sauces to prevent ingredient separation and maintain a consistent quality.
In addition to its thickening properties, CMC is also a popular ingredient in the pharmaceutical industry. It is used in oral suspensions and solid dosage forms to enhance drug release and stability. CMC is often incorporated into ophthalmic solutions to increase viscosity and improve retention on the eye surface. Its biocompatibility and non-toxic nature make it a safe and effective choice for pharmaceutical applications.
